IPC: B29L7/00
Filed: 1993-12-15
Abstract: PURPOSE:To improve the resistance to shaving and scratch of a polyester film by incorporating a fine aluminum oxide powder and a fine chromium oxide powder as lubricants into the film. CONSTITUTION:98-80wt.% fine aluminum oxide powder having a specific surface area of 50-150m2/g and an average particle size of 0.05-0.4mum is mixed with 2-20wt.% fine chromium oxide powder having an average particle size of 0.5 mum or lower to give a lubricant. The lubricant in an amt. of 0.05-1wt.%, if necessary together with other inert particles having an average particle size of 0.3-2.0mum in an amt. of 0.005-2.0wt.% is compounded into a polyester resin, which is then extruded in the temp. range from the m.p. (Tm  deg.C) of the resin to (Tm+70) deg.C to give an unstretched film having an intrinsic viscosity of 0.35-0.9dl/g. The film is stretched monoaxially by 2.5-5.0 times in the temp. range from (Tg-10) deg.C to (Tg+70) deg.C (where Tg is the glass transition point of the resin), then stretched in the direction vertical to the foregoing stretching by 2.5-5 times in the temp. range from Tg to (Tg+70) deg.C, and thermally set in the temp. range from (Tg+70) deg.C to Tm deg.C.

Title: Method for calculating digital controlled variable
Inventor: KUSHIBIKI HIDEAKI
IPC: G05B21/02
Filed: 1990-11-20
Abstract: PURPOSE:To output a correct controlled variable even immediately after a target position changes by not outputting command values to an object to be controlled until all of the deviated values obtained from a prescribed difference equation from the last (m) times of sampling including the current sampling are updated to the deviated amount corresponding to a target value when the target value is newly set. CONSTITUTION:In a digital controller 2 for control, a subtractor 3 calculates the position deviated amount in between a target position (r) and the current position Xn of an object to be controlled, a magnetic head actuator 9, and a command value output bus decision section 4 does not make output from the first to the m-th sampling times when the target position (r) is updated. A command value arithmetic section 5 operates controlling command values and prepares difference equations for the differences between positional deviated amounts ento (en-m) of the last (m) times of samplings including the current sampling and past controlling command values (Un-1) to (Un-n). Therefore, a correct controlled variable can be outputted even immediately after a target position is changed in accordance with a seek instruction, etc., and futile processing time can be reduced further.

Title: Superconducting temperature switch
Inventor: ONISHI YASUTOMO
IPC: H01H3/00
Filed: 1987-12-14
Abstract: PURPOSE:To obtain a temperature switch which is contactless and is not affected by magnetic mutual interference by passing a conductor through a compact which is made of a superconducting material showing a complete diamagnetic phenomenon at an optional temperature, through an insulator. CONSTITUTION:In a superconducting temperature switch 1, a compact 2 becomes complete diamagnetic material below an optional temperature, and the magnetic field for letting a current flow to a conductor 3 passing through the compact 2 is cut off so that the current does not flow to a circuit. Also, although the magnetic field is generated in an insulator, the insulator is thin so that the flowing current can be ignored. Above the optional temperature, the compact 2 loses the complete diamagnetic phenomenon, and thereby the magnetic field for letting the current flow is generated in the compact so that the current flows to the circuit. In addition, as a material which shows a superconductive phenomenon at about an ordinary temperature, SrBaYCu3O7-sigma is known. The material, SrBaYCu3O7-sigma is pulverized/mixed, being burnt in 920 deg.C air for five hours and then pulverized. After the process is repeated three times, the pulverized material is formed and heated at 1000 deg.C for five hours so as to be sintered, and then it is cooled in a furnace. A sintered body made in this way shows the superconductive phenomenon at 388K(65 deg.C).
